LPG

3. By-product during fractional distillation of
crude petroleum oil or by cracking of heavy
oil.
It consists of Hydrocarbons (propane and
butane).
liquefied under pressure.
economically stored and transported in
cylinders.
Its calorific value is about 25,000 kcal/m3

PROPERTIES

14.  LPG consists of hydrocarbons, so it burns cleanly
without leaving any residue.
 The LPG (hydrocarbons) has higher calorific value
than the other gaseous fuels containing H2/ CO.
The calorific value is 7 times higher than coal gas
and 3 times higher than natural gas.
 LPG is characterized by high thermal efficiency and
heating rate
 Environmentally friendly fuel, with minimal sulphur
content and lowest black carbon emission
ADVANTAGES

15.  It is easy to manipulate.
 Comparatively it is less of health hazard, even in
case of leakage.
 Needs little care for maintenance.
 It is free from CO, so it is less hazardous.
CONTI…..

16.  Due to its faint odour, leakage cannot be easily
detected.
 Handling must be done under high pressure.
 LPG is suitable only for the engines working under
high compression ratio.

APPLICATION OF LPG

18. LPG CONVERTION KITS

19. USE: The LPG filler is the gas re
fueling point
LOCATION: Back end. The LPG filler is
permanently mounted to the
vehicle around the same
location as the petrol filler or
fixed to the lower part of the
bumper.
SAFETY: LPG fill connectors feature
one-way safety valves to
enable safe and convenient
refueling.
1. LPG FILLER
Rubber gas pipe from filler to the LPG tank

20. USE: LPG Storage
LOCATION: Back end. There are
two types of tanks
Cylindrical or Donut
type.
The tank is fitted
secured in the boot of
the car.
SAFETY: The tank is made of
High quality steel,
34mm thickness, EC
Approved, secured
with bolts to the floor
of the vehicle and
steel straps.
2. LPG TANK

21. USE: Multi use. Limit the fuel entry to 80% into the tank, LPG
level gauge, Deliver LPG to front end, Pressure release
valve.
LOCATION: Back end. Installed inside the LPG tank.
SAFETY: • pressure relief valve (safety valve) and the pressure
relief device (thermofuse) that in case of overpressure
or fire allow the discharge of LPG from the tank, in order
to avoid an explosion of the tank.
• valve stops the abnormal excess outgoing flow of lpg
• The multivalve is also provided with a shut-off solenoid
valve that allows the lpg flow towards the engine .
• The regulation prescribes that the lpg filling shall stop
when the 80% of the volume is reached; this is obtained
through a 80% device controlled by a float that is
moving inside the tank.
3. MULTIVALVE
Copper or Plastic gas pipe from LPG tank to filter

22. USE: LPG led tank level indicator, Petrol >
Gas micro switch
LOCATION: Inside the vehicle on dashboard
4. LPG DISPLAY

23. USE: The filter removes any dirt in the
gas flowing into the front end
system.
LOCATION: Front end. Engine compartment
5. LPG FILTER

24. USE: Monitors reducer temperature,
reducer pressure, injection rail gas
pressure, manifold pressure, engine
rpm, injection timing. Send signal to
gas injectors.
LOCATION: Front end. Engine compartment
SAFETY: Switch off gas flow in case engine
switches off abnormally.
6. LPG CONTROL MODULE
Rubber gas pipe from filter to reducer

25. USE: Chamber that allow a reduction of
pressure of the LPG and to convert
liquefied LPG to a gas form.
Deliver gas to the injectors rail.
LOCATION: Front end. Engine compartment
SAFETY: Electronic shut of valve
7. LPG REDUCER
Rubber gas pipe from reducer to injection rail

26. USE: Follows signals from LPG Control Module
to inject the correct amount of gas at
the correct timing in the correct cylinder
into the engine trough the injection
nozzles.
LOCATION: Front end. Engine compartment
SAFETY: Continually monitors gas pressure in the
rail.
8. LPG INJECTION RAIL
Rubber gas pipe from injection rail to manifold injectors

27. USE: Inject gas into engine inlet
manifold.
LOCATION: Front end. Engine compartment.
Screwed into engine inlet
manifold.
9. LPG INJECTORS
